Beck Depression Inventory (BDI) is commonly used as a screening for depressive symptoms.

Patients who met criteria for depression with SCID-I and BDI (6.7%) showed a higher score in BDI which did not reach significance. Statistical differences were found in the depressive group. Predictive value of BDI was 6.61% with a cut-off point of BDI ≥ 10, growing to 11.7% with a cut-off point ...
